README
power_monitor/readme.mdPower monitoring acces system
A module based on AndersV209s work on the Wemos D1 Mini based boards. Main changes are:
- DPST relay that breaks both Live and Neutral and handles 8A
- ACS723 10A current monitoring chip
The changes have been done to support use on 3D printers, or other machines where the user won't be expected to leave their key FOB in the device, and where the board can then determine end of use when power draw drops significantly

Questions
How big is the Power monitor PCB?
It measures 60 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power monitor use?
21 parts, built around the HLK-PM01, FDN339AN, G2RL-2A-DC5 and WS2812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Power monitor KiCad files?
From the Hal9k-dk/Access-System repository on GitHub, at the commit this page was made from: the board is power_monitor/power_monitor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power monitor design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hal9k-dk before reusing the design.
